When I do this sort of thing, I usually just use a replace function like
"stringreplace" (from stdlib.ijs), probably already present in your j
locale. For example:
template=. 'Hello {nm},',LF,'nice to meet you.',LF,'{dt}'
template stringreplace~ ,('{nm}';'{dt}'),.'David';'1/1/2013'
Hello David,
nice to meet you.
1/1/2013
The "~" version is nicer because it leaves the constant template on the
left and allows us to more naturally supply multiple arguments on the
right, e.g.
]nmsdts=. >_2<\<;._1 ' Dave 1/1/2001 Fred 1/2/2013'
+----+--------+
|Dave|1/1/2001|
+----+--------+
|Fred|1/2/2013|
+----+--------+
(<template) stringreplace~ &> ,&.>(<'{nm}';'{dt}'),.&.><"1 nmsdts
Hello Dave,
nice to meet you.
1/1/2001
Hello Fred,
nice to meet you.
1/2/2013
